FIELD

The present invention pertains to methods and kits for treating and preventing eye and body conditions and for cleaning eye area tissue. The invention also pertains to a composition of matter usable by the methods and kits.

BACKGROUND

Problems in and around the eyelid can be caused by various diseases or conditions. Causes include seborrheic dermatitis (dandruff), the presence of a bacterial infection (commonly Staphylococcus), a blocked oil gland in the eyelid, food, pollen or other allergies, and ocular rosacea.

Eyelid problems can result in blepharitis, which is an inflammation, often chronic, of the eyelid. Blepharitis is one of the most common eye disorders. Blepharitis can occur in two regions of the eye: at the lid margin on the outside front part of the eyelid where the eyelashes grow (referred to as “anterior blepharitis”) and at the inner eyelid where the moist part of the eyelid contacts the eye and the meibomian (oil) glands are located (referred to as “posterior blepharitis”). Symptoms of blepharitis can include a red, itchy, irritated and/or swollen eyelid, crusting of the eyelid upon awakening, a sensation of a foreign body in the eye, a sensation of burning in the eye, sensitivity of the eye to light, and/or loss of eyelashes.

Ocular rosacea is a condition that affects the eyelids and ocular surface. Ocular rosacea is a long term, inflammatory eye disease that can cause blepharitis and, less commonly, conjunctivitis (inflammation or infection of the conjunctiva that lines the eyelid and part of the eyeball). The presence of ocular rosacea is commonly characterized by irritation, dryness, redness in the eyes, grittiness in the eyes, and/or blurry vision. In more severe cases of ocular rosacea, lid margin and conjunctival telangiectasias (appearance of blood vessels near the surface), eyelid crusts, eyelid scales, corneal infiltrates, corneal ulcers, vascularization, and on occasion, sight-threatening disease occur.

By some estimates, appearance of ocular rosacea correlates with the presence of facial rosacea about 50% of the time. Facial rosacea is a chronic skin condition involving abnormality in the sebaceous glands of the face and eyelids. Facial rosacea occurs on the forehead, cheeks, and nose and is divided into several subtypes, erythematotelangiectatic rosacea (characterized by redness, flushing, and telangiectasias, which is appearance of small blood vessels); papulopustular rosacea, (characterized by small bumps and pus filled lesions-including the presence of papules which are elevations of the skin without fluid) and pustules which are small, inflamed, pus filled, blister like lesions on the skin surface); and phymatous rosacea (characterized by thickened, bumpy skin).

Facial rosacea can affect anyone, but commonly starts in a person after about age 30, and preferentially affects individuals with light colored skin. Facial rosacea is widespread, with an estimated 10% of the American population exhibiting symptoms.

The exact cause(s) of facial and/or ocular rosacea are not known. Cold or windy weather, genetic factors, hot baths, infection with the bacteria Helicobacter pylori (commonly associated with the presence of stomach ulcers), side effects of certain medications, ingestion of hot or spicy foods or drinks, stress, sun exposure, and the presence of Demodex folliculorum or Demodex brevis on the skin of the face and/or eyelid have been proposed as possible causes or triggers for rosacea.

The arthropod Demodex is a tiny ectoparasitic mite that lives in or near skin, hair and eyelash follicles of mammals, including humans. The two species D. folliculorum and D. brevis can co-exist in the face and eyelids, although D. brevis in particular tends to burrow into the eyelash sebaceous glands and the meibomian glands, where it lays eggs. Larvae hatch after about 4 days, and take another seven days to develop into adults. The lifespan of a mite is several weeks. Some data suggest that Demodex mites may harbor the bacterium Bacillus oleronius. One mechanism that has been hypothesized to explain how the presence of Demodex might correlate with rosacea is that the human immune system responds to proteins produced by B. oleronius, resulting in inflammation (see e.g., Li et al., “Correlation between ocular Demodex infestation and serum immunoreactivity to Bacillus proteins in patients with facial rosacea”, Ophthalmology 2010;117:870-877 and references therein).

Although sometimes referred to as “acne rosacea” and confused with acne vulgaris (referred to commonly as “acne”) because both cause irritation to the face, facial rosacea and acne are different, and therefore the treatments recommended to manage them are also different.

Acne is the most common skin condition in the United States. While it can occur at any age, it most commonly affects teenagers and young adults. Facial rosacea is distinguished from acne vulgaris by the presence of non-inflammatory comedones (follicles filled with sebum and sloughed off cells; commonly referred to as “whiteheads” and “blackheads”) with acne and their absence in facial rosacea.

Although acne and rosacea sometimes co-exist in skin, they often occur do not overlap and dermatologists recommend different protocols for treatment of rosacea and acne. The goals with acne treatments are to reduce oil production, speed up skin turnover, control bacterial infection and reduce inflammation. In addition to cleansing the skin, acne may be treated with application of acetone, alcohol, antibiotics, astringents, benzoyl peroxide, retinoids and salicylic acid, and/or ingestion of oral antibiotics, and, for women, ingestion of oral contraceptives. Techniques that cause exfoliation, such as chemical peels and microdermabrasion, may be used.

The effects of acne may be reduced but not eliminated by applying a sufficient amount of tea tree oil. Enshaieh et al. (Indian J. Dermatol Venereol Leprol. 2007, January-February: 73(1):22-25) describe the difficulties of obtaining an acne treatment medicine that has an effect and is tolerated by patients. Enshaieh et al. report use of 5% tea tree oil to treat mild to moderate acne vulgaris and found that 5% tea tree oil was 3.55 times more effective in improving total acne lesions and 5.75 times more effective in reducing acne severity as measured by the Acne Severity Index (ASI). Bassett et al. (Med J Aus), 1990, Oct. 15, 153(8):455-8 examined the effectiveness of 5% tea tree oil in reducing the number of inflamed and non-inflamed lesions in patients with acne. Application of 5% tea tree oil for twenty minutes two times a day for 45 minutes to patients suffering from acne reduced the number of lesions. The tea tree oil acted more slowly than the acne treatment (benzoyl peroxide) to which it was compared. Of note, even using frequent (e.g. twice daily) and relatively long application times over the course of many weeks, 5% tea tree oil treatment was of limited efficacy in treating acne.

U.S. Patent Application Publication 2005/0037034 to Rhoades describes a composition for treating comedonal acne associated with acne vulgaris and inflammatory acne. The composition contains an acne treatment agent together with abrasive particles in a base. A method of using the agent is described. The face is buffed or otherwise treated with the agent using, for example, a hand-held vibratory device. The acne treatment agent can be, for example, benzoyl peroxide, salicylic acid, retinol, hydroxyl acid, or tea tree oil.

Increasingly aggressive acne treatment modalities may be used, as shown by the use of oral medications such as isotretinoin, which has significant side effects on the entire body for individuals whose acne cannot be managed by other methods. Simple, effective and safe acne treatments are still lacking.

These acne treatments tend to be harsh, and harsh treatments have traditionally been thought to worsen the symptoms of rosacea. In particular, because skin affected with facial rosacea is easily irritated, the American Academy of Dermatologists (AAD) recommends gentle face washing for patients. The skin should not be rubbed or scrubbed. Even use of a bath puff or washcloth is discouraged as it can be irritating. Use of alcohol, astringents, clove oil, eucalyptus oil, exfoliants, fragrance, peppermint, salicylic acid, toners, and witch hazel has typically been discouraged.

Facial rosacea patients are advised to avoid “trigger” factors. Topical or oral antibiotics may be prescribed, although it is thought that these are effective due to their anti-inflammatory properties, rather than through their antibiotic properties. Laser treatment may be used to reduce the appearance of blood vessels or other redness in the face.

Treatments of facial and ocular rosacea and blepharitis range from simple over-the-counter treatments to treatment from a dermatologist or ophthalmologist, depending on the severity and duration of the symptoms.

Over-the-counter treatments to relieve the symptoms of ocular rosacea and non-rosacea blepharitis include variations of basic washing and massaging routines. In one typical protocol, the eyelids are cleaned and massaged one or more times a day. First a warm, soft compress is applied to the eyelid for 5-10 minutes. This treatment is thought to loosen the lipids in the meibomian glands. Next, the eyelids are cleaned by gently sliding a cotton swab soaked with dilute baby shampoo across the lid margins. Next, the eyelids can be massaged using a finger or swab moving across the eyelid. While there is individual variation, these treatments may generally be performed over of the course of weeks to months to eliminate or reduce the symptoms of blepharitis. Symptoms of blepharitis tend to recur after this type of treatment and require an additional round or rounds of treatment or a different treatment.

In ocular rosacea cases (and in non-rosacea blepharitis cases) did not respond to the wash and massage treatments, other treatments have been tried. Patients have been treated with medications to manage the inflammation (e.g., eye drops containing corticosteroids), topical or oral antibiotics (e.g., doxycycline, gentamicin, tetracycline, azithromycin) to eliminate bacterial infection, surgery, or chemicals to try to control Demodex infestation.

U.S. Patent Application Publication 2007/0203462 to Soroudi and U.S. Patent Application Publication 2009/0137533 to Adkins describe eyelid treatment kits for improving eyelid hygiene and treating infection and inflammation using antibiotics to eliminate bacterial infection. The kits are meant for treating infection (e.g., blepharitis, meibomitis, acute dacryocystitis, orbital or preseptal cellulitis), treating inflammation (e.g., hordeola, chalazia, or contact dermatitis), treating dry eyes, and/or as post-operative treatment. The kit contains a low dose of an antibiotic (doxycline) and a non-irritating eyelid cleansing composition. Soroudi describes an improved method and materials for use in order to apply heat to the peri-ocular region using a soft, non-abrasive, lint free material such as gauze. The material may contain antibiotics and a cleaner that is gentle to the skin, such as baby shampoo. This material is applied to the eyelid in order to remove bacteria and decrease inflammation.

Other treatments for Demodex involve applying volatile liquids such as ether and alcohol to the eyelid to try to kill the mites. However, there are toxicity concerns with use of these chemicals. Additionally, they were not effective at eliminating blepharitis.

Other treatments for blepharitis associated with a Demodex infestation involve spreading an ointment containing 1% mercury oxide or 2% metronidazole gel or Pilocarpine at the base of the eyelashes. The purpose is to entrap mites as they emerge from the follicle at night.

Kaoukhov et al., U.S. Patent Application Publication 2009/0093421, describes compositions for the treatment of ophthalmic pathologies, including ocular rosacea thought to be caused by infestation of Demodex, using the anti-parasitic agents avermectin and/or milbemycin. The compositions can be applied directly to the eye, or can be solid forms deployed at the surface of the eye in the form of impregnated pads, snydets, and wipes. Kaoukhov lists various additives that can be included in the compositions, including wetting agents, agents for improving flavor, preservatives, stabilizing agents, agents for regulating moisture, pH-regulating agents; buffers; agents for modifying osmotic pressure; emulsifying agents; agents for increasing viscosity; and antioxidants. The efficacy of this as a topical application is unknown and possible side effects due to the use of avermectin and milbemycin are a concern.

More recently, tea tree oil was tested as a treatment for ocular rosacea. Tea tree oil was originally obtained by steam distillation of the leaves of the Melaleuca family of trees, and especially from Melaleuca alternifolia, a tree native to Australia. Tea tree oil can be extracted from members of the Myrtaceae family, including Melaleuca alternifolia, Melaleuca linafolia, and Melaleuca dissitiflora. Tea tree oil contains terpenes (pinenes, terpinene, and cymene), cineole, and an alcohol terpinol. It was used as a traditional medicine to prevent and treat infections. It is thought to have antiseptic, antifungal, and antibacterial properties.

Work from Schaffer C G Tseng (Gao et al., “In vitro and in vivo killing of Demodex by tea tree oil”, British J of Ophthalmology (2005) 89:1468-1473; Gao et al., Cornea “Clinical treatment of ocular demodecosis by lid scrub with tea tree oil (February 2007): Vol. 26(2); Gao et al. U.S. Patent Application Publication 2009/0214676; Gao et al. U.S. Patent Application Publication 2009/0061025; Li et al. “Correlation between ocular Demodex infestation and serum immunoreactivity to Bacillus proteins in patients with facial rosacea”, Ophthalmology 2010;117:870-877) describe reagents, tests, and treatment for patients harboring ocular Demodex. The authors found that application of tea tree oil, caraway oil, and dill weed oil in vitro would kill Demodex. The treatment uses a high concentration of tea tree oil (e.g., 50%) in baby shampoo. The protocol involves cleaning the eyelids and eyelashes with a composition at the doctor's office using a cotton tip wetted in baby shampoo containing 50% tea tree oil. The recommended regimen of six strokes is repeated three times, with a 5-10 minute rest and stroke with a dry cotton tip to remove excess tea tree oil between repeats. The protocol is performed weekly (e.g., for 3-9 weeks) at the clinic. In between clinic visits, the patient continues care at home, generally consisting of daily massages of the eyelids (e.g., for 3-5 minutes) with the fingers using diluted tea tree oil (e.g., 5%) in baby shampoo. The treatment was tolerated by many patients; however others felt eyelid irritation and experienced eyelid spasms during the office tea tree oil treatment. Although the combined treatments rid the eyelids of mites in a majority of the cases, the treatments are inconvenient and costly, requiring weekly visits to the doctor or clinic, as well as additional daily treatments for up to three months. Of particular note, several patients whose symptoms had improved were not entirely rid of the Demodex infestations and continued to have symptoms, albeit reduced, of redness, itching, foreign body sensation, dryness, blurry vision, pain, burning sensation and grittiness even after weeks of intensive treatments.

Microdermabrasion is a technique that mechanically ablates skin. It is used on the face, neck or arms to remove dead or damaged skin cells. It speeds the natural process of exfoliation by mechanically removing the uppermost layer of the epidermis. Microdermabrasion makes it easier for skin products to penetrate into the deeper layers of the skin. Epithelialization and collagen production are stimulated. It is used to counteract the effects of acne and photoaging and reduces acne scars, age spots, enlarged pores, fine lines, and the appearance of blemishes, other scars, stretch marks, undesired skin pigmentation, and wrinkles.

Microdermabrasion uses a device to spray fine microcrystals across the skin surface. This treatment causes superficial abrasion that removes a layer of stratum corneum of the skin. Microdermabrasion is currently contraindicated for an individual suffering from rosacea, seborrheic dermatitis, psoriasis, eczema, or vitiligo, and for any use close to the eye or on the eyelid.

DETAILED DESCRIPTION

A composition of matter according to the disclosure is a novel combination of a microdermabrasive along with a therapeutically effective amount of an isoprenoidal essential oil. The composition may be useful for treatment or prevention of a peri-ocular eye, eyelid, and/or surface ocular condition, disorder, disease, and/or syndrome, and any combination of these conditions, disorders, diseases, and/or syndromes including but not limited to blepharitis (anterior and posterior), Demodex-induced blepharitis, ocular Demodex, dry eye (dry eye syndrome), meibomitis, meibomian gland dysfunction, pre- and post-operative applications, and ocular rosacea.

The composition may be in ophthalmically acceptable base or may be another base. The composition may be applied to the eyelid, eye margin, and/or area near the eyelid, eyebrow area, or to other areas of the face, or to the neck or body.

The invention further comprises kits and methods for treating and preventing a peri-ocular eye, eyelid, and/or surface ocular condition, disorder, and/or disease, and/or combinations of these conditions, disorders, diseases and/or syndromes, including but not limited to blepharitis (anterior and posterior), Demodex-induced blepharitis, ocular Demodex, dry eye (dry eye syndrome), conjunctivitis, blepharoconjunctivitis, meibomitis, meibomian gland dysfunction, pre- and post-operative applications, and/or ocular rosacea. The kits, methods, and compositions may also be used to cleanse an eye area that does not have a disease or condition, such as for regular (e.g. daily, weekly, monthly), occasional, or one-time cleansing. The compositions, kits, and methods may remove body oils or other secretions, detritus, dirt, skin cells, or may remove a substance applied to the eye area such as a cosmetic or cosmetic-related product, including but not limited to adhesive, concealer, eye base, eyeliner, eye shadow, mascara. Use of the compositions, kits, and methods described herein may prevent or solve problems related to the eye that may be an area different than the treatment area, such as eye dryness, grittiness, redness associated with contact lens wear, complications or issues related to ophthalmologic or surgical interventions including laser surgery (such as (LASIK, LASEK, PRK).

In various embodiments, the microdermabrasive and oil may be applied to the eyelid and/or eye area tissue together, or they may be applied separately. FIG. 1 shows a method of eye treatment using an abrasive according to one aspect of the invention. Eye area tissue 2 is being treated in this example. A finger or device may be used to pull the eyelid at least partially away from the eyeball area to prevent cleaning or treatment material from contacting the eyeball or other sensitive eye areas. Hand-held wand 12 has been used to apply a composition 18 of an abrasive material and isoprenoidal essential oil (e.g. tea tree oil) to lower eyelid margin 4 and lower eyelid 10. Upper eyelid 8 and upper eyelid margin 6 have not been treated. Hand 14 is holding and rubbing wand 4 through mixture 18 to chafe, abrade, and cleanse lower eyelid margin 4, including chafing eyelashes 16. After chafing, the abrasive is removed. The abrasive may be removed by any means, including rinsing with a liquid, treatment with vacuum, and/or wiping (e.g. with a cloth, material, towel, or towelette). Prior to treatment with an abrasive, an eye area tissue may be prepared, such as by washing or rinsing (e.g. with warm water).

Prior eye treatments avoided the use of harsh or abrasive materials near the eye for fear of damaging or irritating the sensitive eye. Abrasive materials, in particular, have been avoided for use near the eye. The novel use in the invention of an abrasive or microabrasive near eye tissue, in combination with an isoprenoidal essential oil, according to one aspect of the disclosure, may allow a lower level of isoprenoidal essential oil to be effective. The use of a lower concentration of oil, in combination with an abrasive or microdermabrasive, may be more effective, safer and less irritating for a patient than is use of a higher amount of oil without an abrasive. In some cases, the treatments may be sufficiently safe to be self-applied by the patient without requiring treatment in a medical setting (e.g., a clinic or physician's office) such as after an initial visit with a physician or other health care provider. In some cases the material may be sufficiently safe to be available over-the-counter and the method used by a patient or individual without requiring a doctor or clinic visit. An option for convenient and inexpensive self-treatment is desirable in any case and may be particularly advantageous for patients who have chronic and/or long-term conditions, and for patients for whom conditions recur after an initially successful treatment regimen. Eye conditions and symptoms may recur in an individual due to a new exposure to a causative agent. For example, Gao et al. (Cornea, Vol. 26, No. 2, February 2007:136-143) recommends that a patient being treated for Demodex discard make-up and weekly wash their bedding and pillowcases in hot water to prevent re-exposure to Demodex. These steps may not be sufficient and may be inconvenient. The compositions, methods, and kits according to the disclosure may be used at home or in a salon or other personal care setting, and may be applied by the individual, a helper, or a facial aesthetic specialist.

While not limiting the method of action of the treatment, it is thought that the treatment acts to remove skin, a layer of skin, skin debris, micro-organisms, eyelashes, oils, and/or other related or unrelated substances. The abrasive particles are thought to work by mechanically agitating the eye area tissue, eyelid, eyelash, and follicle to improve penetration or access of the oil. The treatment may work to agitate or move unwanted material such as Demodex eggs, larva or mites and remove them from the eyelash follicle or other part of the eye or eyelid, or to make them accessible to the oil. The dermabrasive may also eliminate organisms by direct killing or damage.

FIG. 2 shows a perspective view of an eyelid margin and a posterior eyelid margin treatment with an abrasive and isoprenoidal essential oil. Meibomian glands 56 are blocked, for example by secretions or dirt. Head 52 of wand 50 is chafing posterior eyelid margin 38 on lower eyelid 30 with mixture or composition 57 of abrasive and isoprenoidal essential oil. The treatment is cleaning blocked meibomian glands surface 56 resulting in unblocked or opened meibomian glands 42 and allowing fluid, debris, oils, sebum or micro-biologic material to escape from meibomian glands 48, shown in a cross sectional area of the eyelid in this drawing. Inflammation, irritation, redness and other symptoms and problems may be reduced. Chafing may also or instead be performed along anterior eyelid margin 36, shown on the other side of grey line 40 from the posterior margin, to clean margin surface and eyelash 44. Chafing may also be performed on lower eyelid skin 32. Conjunctiva 34 is free from treatment. Rubbing, chafing, or otherwise agitating posterior eyelid margin, anterior eyelid margin, eyelid skin, and/or other eye area tissue may move eyelash follicle 46 or may move other structures at or below the surface. This agitation along with the chafing may improve or allow flow of body oil, sebum or micro-biologic material out of tissue and may allow penetration of cleansing media or oil, such as isoprenoidal essential oil, into tissues.

The abrasive may include any abrasive particle, powder, or crystal including but not limited to one or more of the following: aluminum oxide (e.g., alumina, aluminum trioxide, corundum powder), barium sulfate, boron nitride, calcium carbonate, cellulose acetate, ceramic, diamond, diatomaceous earth, emerald, ethylene/acric acid copolymer, fibers, garnet, glass, kaolin, lauroyl lysine, lava, magnesium oxide, mica, modified starch, nylon, other metals, other polymers, other silicon dioxides or silicon containing materials, polyethylene, polymethyl methacrylate polypropylene, polystyrene, polytetrafluoroethylene (PTFE), pumice, ruby, sand, sapphire, seashells, sericite, silica, silicon dioxide, silicon carbide, sodium bicarbonate, sodium chloride crystals, starch, silk, talc, topaz, zeolite, or polymer particles. In one embodiment, Kiehl's Epidermal re-texturizing micro-dermabrasion formulation may be used.

An abrasive particle according to the disclosure may be any shape and have any number of sides. An abrasive particle may be overall diamond (triangle) shaped, elliptical, marquise shaped, octagonal, oval, pear shaped, rectangular, round, squared, or may be combinations or variations (e.g. a rounded square) of these shapes. An abrasive particle may have one surface or may have more than one surface (e.g. sides or faces). An abrasive particle may have 2, 3, 4, 5, 6-10, 11 to 20, 21 to 30, up to 40, up to 50, up to 60, or more than 60 sides. A surface of an abrasive particle may be substantially smooth, regular, textured or irregular. An abrasive particle may have one or more sharp edges or points.

An abrasive particle may be sized from about 1 to about 600 microns (1 μm to 600 μm) across a longest dimension.

Abrasive particles in a group may all be similarly shaped to one another or may be differently shaped from one another. Abrasive particles in a group may all be about the same size, or may range in size. A group of particles may be larger than a minimum or may be smaller than a maximum. A group of abrasive particle may include particles from about 1 to about 15 microns across, about 15 microns to about 25 microns, about 25 microns to about 100 microns, about 100 to about 300 microns, or about 300 to about 600 microns. In one example, a group of abrasive particles may include particles from greater than about 25 microns to less than about 300 microns across. Differently sized and differently shaped particles may be chosen for different reasons. Different sizes and shapes may be chosen for different eye area conditions, different skin types or sensitivities, and/or different methods of application. A particle with a rough surface may be applied using a wand or towelette, while a substantially round particle may be propelled towards the surface under pressure.

An abrasive may include a group of separate particles, or may include a substrate with an abrasive surface or may be any combination or variation. A substrate may have a plurality of abrasive particles connected with (attached to) it to provide an abrasive surface, or it may be a material having a rough textured surface. A rough textured surface may have a pore size on its surface from about 1 to about 15 microns across, about 15 microns to about 25 microns, about 25 microns to about 100 microns, about 100 to about 300 microns, or about 300 to about 600 microns.

The amount and composition of the abrasive in the compound is chosen so as to have the desired effect while minimizing unnecessary abrasion, damage or irritation to the eye region or sensitive peri-ocular region.

The product and method of this disclosure may be used in conjunction with chemical exfoliation, chemical peel, crystal free dermabrasion and/or laser resurfacing.

One or more isoprenoidal essential oil may be included in the composition along with an abrasive. The list of essential oils includes but is not limited to those described in U.S. Patent Application Publication 2009/0214676 to Gao et al., which is incorporated herein by reference. 1,4-cineole, 1,8-cineole, (4R)-limonene 1,2-epoxide, 3-isopropoxyphthalide, 3-propoxyphthalide, 6-terpinolene, 7-methyl-3-methylideneocta-1,6-diene (myrcene), acetaldehyde, alpha-pinene, alpha-terpinene, alpha-terpineol, alpha-thugene, caraway oil, cardinene, (+)-carvone, (+)-cis-limonene 1,2 epoxide, cuminic aldehyde, d-carvone, dill seed oil, dill weed oil, dipentene, dipentene (+/−)=limonene, eucalyptol, furfurol, gamma-terpinene, 1-carvone, (+)-ledene, (+)-limonene, (R)-(−)carvone, (R)-(+)-limonene, myrcene, para-cimene, (S)-(+)-carvone hydrate, Tea tree oil (Oil of Melaleuca), terpinen-4-ol, and/or variations and/or pharmaceutically accepted salts thereof may be added. The concentration of the oil(s) in the formulation may be any safe and effective amount. Higher concentrations may be more effective but may be administered by a health care professional to ensure safety.
